METALLIC CAR-ROOF.

Specification of Letters Patent.

Application filed July 3, 1812. Serial Ho. 767,415.

T 0 all whom it may concern Be it known that I, HENRY A. CHRISTY, a. citizen of the United States, residing at Kenilworth, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Car- Roofs,'of which the following 15 a specification.

My present invention relates more especially, but not exclusively, to the mechanical constructions of the roofs of railway cars. 7

For some time, various types of metal roof-structures have been devised, but in several ways these structures have failed to fulfil all of the various requirements to the best advantage, and it is, therefore, one of the objects of the present invention to supply a roof-structure which shall be simple in construction, economical to manufacture, easy to repair, and less subject to damage than a has heretofore been usual.

'With these objects in view I have devised as embodin'ients of this invention the structures illustrated in the accoinymnying drawings forming a part of this specification, end to which reference should be made for it full and complete comprehension of the features of structure involved.

In these drawings; Figure 1 is a fragmentary perspective view of one embodiment of my improved roof; Fig. 2 is a cross section through the same; Fig. 3 is an end elevation of the roof-structure; Fig. 4 is a fragmentary side elevation: Fig. 5 is a cen tral longitudinal section; Fig. 6 is a fragmentary cross-section on an enlarged scale;

. Fig. 7 is a similar section through a differcnt plane; Fig. 8 is across-section. through the central portion of the roof; Fig. 9 is a longitudinal section at one side of the cen tral plane of the car; Fig. 10 is a fragmenta ry perspective view of one/of the caveslrips; Fig. 11 is an end viewof the cavestrip shown in Fig. 10; Fig. 19. is a perspective View of one of the braces; Fig. 13 illustrates in cross-section a modified form of roof structure embodying this invention; Fig. 14 is a fragmentary horizontal section online 14-14 of Fig. 13; Fig. 15 is a detail section through one of the carlincs, the roofplates and cap-strip; Fig. 1G an enlarged cross-section of a still further modification, and Fig. 17 is a horizontal section on line 17--170f'Fig. 16.

By reference to the drawings and more particularly to 1 to 12 inclusive, it will be apparent that the car structure, as is usual. has a car-body end-wall 20 and sidewalls 21 and 22 at the tops of which' are disposed the horizontal side-plates 23 and 24. Along the tops of these side-plates 23 and 9A and the top edges of the side-Walls or sheathing Z1 and 22 are disposed longitudinal metal cave-strips 25, each having at its outer edge a depending flange 26 overlap-. ping the top portion of the car-body sidewall, all as is clearly illustrated in Fig. 2. At its inner edge, each of these cave-strips has an upstanding flange 27 bent at intervals at 28, as shown in Fig." 10 for the accommodation of the carlines and roof-plates described hereinafter. At each end," each of these cave-strips has a downturned flange 29 fastened at 30 to an inturned end of the flange 26 to form a neat and substantial corner.

Suitably spaced apart, and accommodated at their ends in the depressions 23, are channel carlines 31 each having, as is shown in Fig. 9, a web 32. a pair of upstanding still"- cning walls 33 forming the trough of the (:H'liilt. cuch of such walls at its upper edge having outstanding bracing flanges 34. These car-lines, as is clearly shown in the drawings, are of the cambered or bent formation so as to provide a roof of double slope with suitable and suflicient inclination for drainage purposes. v At each end, each of these oarlincs terminates in a flat ear 35 adapted to rest on the tops of the cave-strips Inasmuch as this structure does not have a ridge-pole. and in order to addition ally stitien and strengthen the framework, ea h cal-line at each end is-connected to the car-body sidewall by a shaped sheet-metal bracket or brace 36 of the conformation as shown in Fig. 12. Such bracket has an apertured flat plate-portion 37, adapted, as is shown in Fig. 6, to lie against the inner face of the correspoi'lding side-plate 23 or 24. On its top this'bracket 36 has a channel-p0rtion 39 adapted to fit about and accommodate the end-portion of the carline, the two apertured portions 39 and 40 lying directly beneath the oppositely-disposed flanges 34, 34 of the carlines to which they are fastened by suitable rivets 41, 41. is shown. each of these brackets is. when in place, of general inclined disposition, the surface 42 being disposed directly beneath the inclined wall of the depression 28 of the cave-strip. T he two substantially horizontai flanges 39 and 400i the bracket are, as

ran-med July 22,1913.

is illustrated, connected to the plate by flaring wings or gussets 43, 43 for obv ous stiffening and bracing purposes.

bracket-plate 37 is fastened against the inare covered with bent metal caps 52 of inverted channel shape, such cap-strips. as

shown in Fig. 1, extending from side-wall By means of bolts 44 passing through the sideplate and the car-body side-wall, the

ner face of the side-plate, and by means of another bolt 45 extending through alined j apertures in the flange 26 of the eave-strip,

the car-body sidewall, the side-plate, and the bracket or brace is additionally secured in position. Each of these brackets not only assists in supporting the carline'in position, but as will be clear, it also braces it and stifiens 1 against lateral displacement, so that the whole car-roof framing, even though it has no ridge-pole and is composed substantially of carlines extending from side-wall to side-wall suitably braced, presents a firm, rigid and secure structure for holding in position the roof-plates and other appurtenances of the roof-construction.

Each of the sheet-metal roof-plates 46, 46 extends from side-wall to side-wall and is bent across its middle to give it the proper camber or shape to conform to that of the carlines. Along its longitudinal edges each of these plates has a depending flange 47 accommodated in the troughs of the carlines, the lower edges of such flanges resting upon the webs of the carlines, the flanges being of sufiicient width to support the roofplates above the edges of the flanges 34: of the carlines, so that Whatever wear takes place does not occur between the roof-plates and the carline flanges. Furthermore, these roof-plate flanges 46 are spaced away from the corresponding walls 33 of the carlines whereby to give the roof a certain and adequate degree of yield or flexibility so that it may accommodate itself to uneven loading of the car-body and uneven settling or defleet-ion of the car-body walls without tearing or otherwise injuring any of the plates. Each of these roof-plates at its outer ends bent down to form a sloping flange or wj'all 4S terminating in a narrow fiat-non tion 4 resting directly on the body-section or wr-lrportion of the cave-strip.

The advantage of the association of the root-plates, troughed carlines and cap strips. substantially as described, in shed- (ling water is obvious. and it shouldbe apparent that any water which might find its waya under the capstrips from a driving.

rain-storm or from sndw or ice being frozen on the roof and acting as a dam will be promptly carried off by the channel or trough of the carlines.

Above each earline and partially housed within the same between the flanges of the motplates, I employ wooden fillers or strips 50 having central depending portions 51 fitti' H9 in. holes between such roof-plate flanges.

he tops and sides of these wooden strips to side-wall and terminating in flat cars 53 disposed above the attachment-ears 35 of the carlines, and in order to fasten these capstrips, carlines, and,eave-strips in proper position, to the tops of the.car-body.sidewalls, I provide each cave-strip at intervals with apertures surrounded by marginal upstanding rims or flanges 54, which extend upwardly through registering holes in the cars 35 and 53 of the carlines and cap-strips respectively. Extended. through each of these carlines, and also through an alined hole 55 of the-side-platc, is a bolt having a mushroom head between which, and the upppr edge of the rib 51 is interposed a soft copper washer forming a water and moisture-tight connection between the parts. The nuts 57 for such boltsrare on the inside of the car and bear against the bottoms of the side-plates so that these series of bolts hold the parts of the roof in place in such a manner that they may be detached andremoved with facility and despatch, and yet at the same' time, these holding and securing means do not project outwardly beyond the side of the car-bod v, where they would be subject to side-wiping.

As is clearly. indicated in Fig. 1, each of the sheet-metal roof-plates at the end of the car-body has on one side a flange received in the trough of the next adjacent carline, I as do the other roof-plates, but at its'opposite edge at the end of the car-body, it is supplied with a flange 58 overlapping the end-wall of the car and fastened thereto by any suitable means such as bolts or screws .stanec, are fastened to and supported by the channel metal coverings forming parts of the cap-strips over the carlines. At the center of the roof, each of the wooden-fillers 50 is recessed as shown in F ig. 8 at 62 for the reception of the head of a bolt 63 adapted to detachably fasten to the metal cap-strip 52 a supporting-block 64, preferably of wood, and shaped on its under surface to conform to the double inclination of the roof so that the lower edge of such support rests directly on the oppositely inclined portions of the metal cap-strip 52. To the top edges of these various supports 64, I fasten the 'rumiing-board planks 65 which he made in sections, if desired, and a re prelerably made readily detachable:
